2. Material and ingredients
2.1 materials the materials used in the preparation of test 2 including parts of the total mass and rough materials geopolymer paste
2.1.1 coarse aggregate is heavy ash from lignite power plant, MOH Characteristics of bottom ash holding into cubes. Sub sub machine used with smaller size and a size between 4.75-9.50 mm.The characteristics of a coarse aggregate to be angle, rough skin, and has high porosity, as shown in รูปที่ 1 physical properties and chemical composition of bottom ash is shown in Table 1.ASTM C127 [15] has the weight in saturated surface dry, as 1175 kg / M 3 precious water absorption was 3.86 percent. From the test and the wear and tear Los Angeles standard ASTM C131 [] is equal to 39 16 erosion.4 percent. When compared with a natural limestone aggregate Overall gross weight and ash will be strong less because the meat porosity than
.Figure 1 Characteristics of coarse ash weight, through digestion and sizing
2.1.2 Geopolymer Material paste. Materials used as components of geopolymer paste including
.- fly ash from Mae MOH, Lampang, table 1 show the physical properties and chemical composition of fly ash, according to the standard ASTM. C618 [17] showed that the fly ash in the volume, Class C SiO2And Al203 Fe203 include 68 percent by weight (Class C quantity, and SiO2 Al203 Fe203 included between 50-70 percent โดยน้ weight).
- sodium hydroxide (NH) concentration and molar 10 15
.- sodium silicate solution (NS) table 2 show properties of matter
- Portland cement Type 1 standard ASTM C150 [] is 18 resolution. (Blaine fineness) 3 120 cm, 2 / g test according to the standard ASTM C204 [19] and the specific gravity 3.15 test according to the standard ASTM C188 [20]
